IFTTT (short for "If This Then That") is an American workflow-automation platform founded in 2010 by Linden Tibbets and Jesse Tane that lets users connect web services, devices, and APIs into single-step trigger-and-action rules called Applets — for example, "when I'm tagged in a photo on Facebook, save it to Dropbox."
The platform was an early consumer entrant in what became the broader low-code workflow-automation category alongside competitors like Zapier and Microsoft Power Automate, with a particular early focus on consumer Internet-of-Things devices (Philips Hue, Nest, August Locks, Roomba), social media, and household productivity tools. IFTTT pivoted toward a paid Pro tier in 2020, repriced the free product down to a small handful of Applets per user, and now positions itself with a substantial enterprise integrations business in addition to the consumer surface that originally made the brand visible.
